Exposed expanded Group A plastics rack storage represents a growing challenge for sprinkler protection in warehouses. A new research report has been published that looks into this issue, titled "Protection of Expanded Group A Plastics," authored by UL LLC.
This report presents the results of eight full scale fire tests that explore the effectiveness of the combination of an innovative vertical barrier protection feature with ceiling only sprinkler protection. The project objective was to develop cost effective sprinkler protection criteria for rack storage of exposed expanded Group A plastic commodity with a particular focus on ceiling only protection.
Take a look at the results from all eight tests as well as their findings by downloading the report from the Fire Protection Research Foundation site.
